Hi

So I need to be flexible with the specification of input and
output parameters for these programs. But I see some software
development challenges for this use case.
I'm sorry but I don't really understand what you're trying to do.
How do you think about to share any more software

You mention a construct define … endef
I assume that you want something different from this
but you need to explain better, sorry :-)
I hope that an other wording will be clearer.
Can make rules be extended on demand while a build script
is evaluated?
How much can a command like getconf _NPROCESSORS_ONLN
influence rule evaluation

experiences for the application of the command getconf
_NPROCESSORS_ONLN together with make tools?

It seems like you want to automatically expand or contract the
number of jobs that make will run in parallel,
Yes, exactly.
I can not use the parameter -j directly for the start of the main
make process in my case so far.

One of the variables (or

$(eval) lets you generate rules dynamically.
Does it really support the generation of completely new build rules

I guess I don't really see what the purpose of this is. If you have 2
CPUs you get targets MYTARGET_0 and MYTARGET_1. If you have 4 CPUs you
get targets MYTARGET_0, MYTARGET_1, MYTARGET_2, MYTARGET_3.
So... then what?
I need to find some source files before I can start further processes
The corresponding processes should be efficiently started for
parallel background execution after a serial data preparation
was finished.
This makes very little sense.
This issue depends on work flow ordering.
In a properly written Makefile, your serial preparation step
will remain
Hello,
I would like to use all processor cores for a software build.
So I try to reuse a corresponding system setting by a command
like getconf _NPROCESSORS_ONLN in recipes for a make file.
A bit of build preparation needs to be performed in a serial
way before I can begin the desired parallel
